Description

[0001]
TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed document sealing device for sealing a document output from a facsimile or a printer so that the document cannot be seen by a third party.
[0002]
[Problems to be solved by the invention]
When receiving a message or e-mail from a specific party by fax or PC printer, depending on the content, there are some inconvenient parts that can be seen by a third party.
However, conventional faxes and printers leave printed documents as they are, so if a large number of people share a fax or printer at a company, etc., they will remain confidential until they are abandoned or delivered to the person. Third parties may be able to see what should be done.
[0003]
SUMMARY OF THE INVENTION The present invention has been made to prevent the contents of a printed document from being viewed by a third party when necessary when many people share a fax or a printer.
[0004]
[Means for Solving the Problems]
In order to achieve such an object, the present invention is configured as follows.
[0005]
That is, the print document sealing device of the present invention includes a determination unit that detects a control code and determines whether or not a seal is necessary at a subsequent stage of a printing unit that prints and outputs a print document, and seals the seal paper at a predetermined timing. The above object is achieved by providing a feeding means for feeding out and a sticking means for sticking the fed seal paper to the printed document.
[0006]
Preferably, the control code is image information written in a predetermined place of a print document.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0008]
FIG. 1 shows a configuration diagram of a print document sealing device embodying the present invention.
The seal device for a printed document includes an image processing unit 1, a memory 2, a printing unit 3, and a sealing unit 4. The print data transferred to the printer is converted into a dot image by the image processing unit 1, and the converted image is stored in the memory 2. accumulate.
The dot images stored in the memory 2 are sent to the printing unit 3 and printed on print paper, and the printed print paper is conveyed to the seal unit 4.
At this time, the dot image is analyzed to determine whether or not there is a marker that requires a seal at a predetermined place in the print data. If there is, a request signal for performing a seal is issued to the seal unit 4 to seal the print paper. I do.
[0009]
As shown in FIG. 2, a marker that requires a seal is represented by image information by, for example, inserting a large black circle or a thick line at a predetermined position of a fax or e-mail transmission original or enclosing both sides of the seal portion with a thick line. indicate.
This eliminates the need for a special device such as a button for designating the necessity of the seal on the transmission side, and thus enables the necessity of the seal to be specified for a document transmitted from a normal fax.
Instead of detecting the marker by analyzing the dot image as described above, the marker once printed on the print document may be detected by using an optical sensor or the like.
In this case, a print document output from a normal facsimile or printer can be input to an external seal unit to be sealed.
[0010]
FIG. 3 shows a schematic view of a seal portion embodying the present invention.
The seal portion 4 is configured to feed out a roll paper 41 having a seal paper a adhered to a liner (release paper) b with a sprocket 42. A tension roller 43 and a blade 44 are arranged on the way, and as shown in FIG. When folded by applying the blade 41 to the blade 44, the seal paper a is peeled off from the liner b, and the seal paper a is wrapped around the pressure roller 45 and pressed to be bonded to the printed document c moving in the direction of the arrow in the figure.
[0011]
When receiving the seal execution request signal, the seal unit 4 drives the sprocket 42 to attach the seal paper a to the print document c.
The drive timing of the sprocket 42 at this time is detected by a passage sensor (not shown) provided on the conveyance path of the print document c.
The sprocket 42 is driven by using a high-precision step motor (not shown), and the amount of the roll paper 41 fed out is controlled by the rotation speed of the step motor, and the rotation speed of the step motor is controlled by the number of drive pulses. .
[0012]
The roll paper 41 is formed by arranging fixed-size seal papers a at equal intervals and adhering to the liner b, winding the rolls into a roll, applying an adhesive to the seal paper a, and affixing the seal paper a to the liner b.
The adhesive is of a re-peelable type such as rubber-based, acrylic-based, or silicone-based, and is designed so that it can be smoothly peeled off from the adhered partner and does not damage or contaminate the partner when peeled off.
The liner b is made of a high-quality paper laminated with polyethylene and subjected to a silicone release treatment, so that the seal paper a adhered to the surface can be easily peeled off. As shown in FIG. 5, the print document c has a configuration in which a communication column is provided below a header portion describing, for example, a destination, and a sticker a is attached to the communication column to seal the entire communication message.
[0013]
As shown in FIG. 6, the seal unit 4 is configured to store a cut sheet of the seal paper a in the hopper 46, feed it out by the paper feed roller 47, wind it around the pressure roller 45, and bond it to the print document c while pressing it. It may be.
The drive timing of the paper feed roller 47 at this time is similarly detected by a passage sensor (not shown) provided on the conveyance path of the print document c.
In this case, the seal paper a is obtained by subjecting the back surface (surface substrate) of which the adhesive is applied to the back surface to a silicon peeling treatment.
[0014]
In the present embodiment, a message is sealed by sticking a predetermined size of seal paper a to a predetermined position of the print document c, but a cutter for cutting the seal paper a to an arbitrary size, and a print document c And a control system for controlling the feed amount of the sprocket 42 to an arbitrary length by attaching a seal paper a of an arbitrary size to an arbitrary position and printing a printed document c. The parts to be concealed may be individually sealed.
[0015]
The print document sealing device embodying the present invention is configured as described above. When the dot image is analyzed and a marker requiring a seal is detected, the timing of feeding out the roll paper 41 by a signal from the passage sensor of the print document c. Is detected, the sprocket 42 is rotated, and the roll paper 41 is fed out by a predetermined length.
Thereby, when the roll paper 41 is folded back by the blade 44, the seal paper a is peeled off from the liner b and is pushed forward, merges with the print document c passing under the blade 44, and adheres to a predetermined position of the print document c. .
At the same time, it is entangled by the front pressure roller 45 and moves together with the print document c, and is pressed by the pressure roller 45 during the movement to be securely glued.
[0016]
【The invention's effect】
As described above, according to the present invention, a document output from a facsimile or a printer is sealed by putting a marker that requires a seal on a transmission document, so that many people can share a facsimile or a printer with peace of mind. Various messages and correspondence can be output and received by fax or printer.
